Be it known that I, Jaooi; FRANKLIN Nisn- WANGER, a citizen of the United States, and

v a resident of Tranquillity, in-the county of Fresno and State of Galifornia,;haveinvent ed a new and useful Improvement in' Differentials for Vehicles, of whiclrthefollowing is a specification. r r I My invention relates to differentials in vehicles in which the motive power is transmitted through shafts carrying traction K wheels, such shafts being divided into two parts and means whereby the differential can be adjusted, so that one ,part of theishaft can have, a more positive pulling power than the other-part of the'shaft. I

w The primary object of my'invention isto I'produce a differential adapted to -transmit power to a shaft divided into two parts wherein the driving power can be applied to a greater degree on one side than the other, wherein the division of thepower as between the shafts can be varied at the will of, the

operator, and more in detail the application ofthese objects is to permit the wheel on one end of the shaft or, aide to have a greater traction powerthan its mate, so that thepull v of the tractor can be placed nearer the wheel having the greater traction power. And in cases where it is proposed to drive the front and rear wheels with'a differential betweenthem, adjustments may" be had whereby the driving power applied to oneset of wheels can be greater than what is applied to the otherset. Other objects will be hereinafter disclosed. 1 Y I These are accomplished by means of the device illustrated in the enclosed drawing in sembly of the'master gear and intermediate gears partly in section.' ,-Figure 3 is a view] "of a modified form of'differential partly in section, showing a floating axle "carryinga which Figure 1 shows a sectional view of the differential complete. Figure 2 shows the as ,angular in shape.

To

the sleeve K are rigidly attached a plurality, ;of uniform-sized pinions which are used as intermediate pinions in the differential In 7 Figure 1 I have shown three pinionswhich are identified as 8, 4L and 5 and in Figure 3 I haveshownbut two,indicated as 4E and5.

The relation of the gears'described are that the driving gears G and G are adapted. to mesh with pinions 5, driving gears F and F3 are adapted to mesh with pinions 4 and driving gears E and E aread'apted to mes h' with pinions 3.' By means of thesliding sleeVesGr and-Gr? F -and"F E 7 and Ef these driving gears and, intermediate ,p n ons can be enmeshed or disengaged and different 7 combinations may be, formed whereby the .larger drivinggears On the one side may be enmeshed vwith one of the" intermediate pim ions attachedto sleeve Ki and a smallerdriving; gear on the other side enmeshedwitha pinion on-sleeve K, thus making the pulling power on the shafts B and B? unequaL- fIt should'be noted that thedrivinggeai"s;F,.F -r' I E and E are formed cup-shaped so thatthe 7.

smaller gears can be] disengaged from the pinions onsleeve K by being slid into the" cup portion of thelarger wheelsj while the larger wheels can be ,enmeshedwith the pinions on sleeves K.

I have placed, a series" of holes the sleeves described-for thejpurpose of lock- 1 ingthe: sleeves carryingthe driving gearsby means ofa pin 8 in anycombination which may be selected The hole throughethe axleis designated as 6 and. the other holes'as hereinafter referred to. When b01616 registers with holes 6 iii-sleeve G,- with hole 6 in sleeve F andwith hole 6 .in:sleeve -E -the driving garG white in ineshvvith .pinions.;,j

,5 and driving gears F and E will be idle.

If under those conditions the driving gear G is also enmeshed with pinion 5, the pulling power applied to shafts B" and B are approximately equal.

- When hole 6 registers with hole 16 on this adjustment, if driving gear G is en meshed with intermediate pinion 5, a greater traction power will be transmitted to shaft Bthan to B VVh'cn hole 6 registerswith hole 16", in sleeve Efland with holes 16 and 6, the driving gear E will be in mesh with intermediate pinion 3- and gears G and F ,will be idle. -Driving gears G and F and E can be adjusted in the same manner as gears G, F and E herein described. It should be noted that no special claim isinade herein for the device for shifting the sleeves described; Any of the usual devices for shifting gears and locking them in selective relations can be applied to and used in the shifting of the driving gears above described.

In Figure .3 I haveslhown another form of differential in'inore common use in which the same principle of unequal. sized driving gears being used is involved. In said Figure 3, O is a differential box carrying j shafts O on which sleeves la are disposec to rotate. Sleeves K carry intermediate pinionse and 5 which are attached thereto. -M and M are shafts having a common center line, each' of which have an end within the box 0. Shaft M has attached thereto Within box 0 a driving gear R which me'shes with pinions 5, and shaft M has attached thereto driving gear which also I meshes with pinions 5. N and N are sleeves fitted to slide on shafts M and M. Sleeves N andfN each carry a cup-shaped driving gear Q and Q of uniforinsize, gears Q and Q are adapted to mesh with intermediate gears stand by sliding the sleeves N and N gears Q; and Q and intermediate pinions t can be disengaged. The sliding of the sleeves N and N and sliding shafts M and M and locking'tl'iem in selective positions canbe done in any suitable manner;
